"I raced the quartermile last week in Canada and last month in Australia, but I haven't raced the quartermile in the United States since NHRA changed the rules on that, so that goes back to 2008," Dixon said of the sanctioning body's decision to go to 1,000 feet racing. "It's been a little while since I've been able to air it out in our country, so I'm definitely excited about that opportunity.

"As a competitor, whatever it is, you are going to try to be the quickest. But I think (the quartermile) is what most people can relate to. Being able to go to a facility that is in position to let us run the quartermile, I love it."

I saw the car on Tuesday and told Larry this is the greatest marketing tool for sponsors I've ever seen. And I'm really, really tempted to spend the money to ride this thing. But I'd want a full 1000 ft pass.

I think there is some bad blood between Mr. Dixon and NHRA. Remember when he was asked to remove the decals at Gainsville. Perhaps politics have also entered into this scenario, perhaps someone with Traxxis ties complained and made it an issue.
Not sure how much modification can be done to a chassis before the "tag" would need re-certified.
Glad to see Mr. Dixon try something new, NASCAR has 2 seat cars and Mario Andretti had a 2 seat Indy Car, have also seen a 2 seat sprint car so why not.
